I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

 Estava utilizando meu notebook só na bateria, apareceu a mensagem que estava quase acabando, mas não conectei, fechei a tela e deixei para trabalhar no outro dia, quando conectei o carregador e apertei o botão de Power, não ligou e nem apareceu sinal nenhuma que está ligado na bateria ou outra forma. Já fiz o procedimento de limpar a energia segurando o botao de Power com ele desconectado mas continua sem sinal algum, também ja testei outro carregador.

A problem has recently developed with my Envy notebook.   About 2 weeks ago my entire wireless network began slowing down when on it.   Noticeable on all devices.    When my provider came out, checked and tweaked some issues it appeared to be ok.   I went on with my daughers HP laptop and was drawing 20-24 mbps all over the house. When I reconnected mine to the system I was only pulling 6, 3, 5, up and down.   It doesn't start right away but after a few minutes.   So I put my duaghers right next ot mine and low and behold, when I ran her's it pulled 3 - 6 also.   So I turned my wi-fi off and hers' popped right back up.   I have also tried this with an old XP mini, my i-pads etc.   As soon as mine gets on the network the speed crashes.    This also happens with no one else home and no other devies conncted. I have downloaded the latest up to date Intel driver for this network adapter and it hasn't changed anything. Any ideas?

Bill_Ving Hello;Allow me to welcome you to the HP forums!I read your post about wireless networking poor performance and wanted to help. My immediate guess is that you might have mixed-mode networking going on.  This happens when you have two different PCs networking in two different modes -- one using "G", the other using "N".  The wireless router (or access point) can optimize performance for either mode, but not for both.  So, the "G" mode drags down the performance of the "N" mode PC, but even worse, with the router set for mixed modes, it performs more slowly than with either PC connected by itself.Here are some other troubleshooting steps you can try: HP PCs - Troubleshooting Wireless Network and Internet (Windows 8) | HP® Customer SupportGood Luck========================================================================I am a volunteer and I do not work for, nor do I represent, HP.---------------------------------------------------------------Please click "Accept As Solution" on the post that solves your issue to help others find the solution.Please click the Thumbs-Up symbol on the left of the Reply button to say thanks fopr my help.========================================================================

I made a Google notebook to keep the minutes of a meeting my business partners and I held last weekend. I made them all collaborators on the notebook so they could all make any changes or annotations they felt necessary. However, when they go to access this notebook they are prompted for a password.

There is nowhere (at least that I can find) to even choose to password protect the notebook let alone change the password. I'm pretty confused as to what password the notebook could be. The only thing I can think of is that it's asking for the password to my gmail account, which I don't really want to be handing out. Any ideas on this one gang?

My wife has a two-year-old Samsung notebook. Recently when she unplugged it the machine cut off, even though the battery said 79% charged (it wouldn't charge any further). I figured that the battery was bad so I bought another one from Amazon.

This one charges to 100% percent and does exactly the same thing. I'm perplexed but think there's something going on with the motherboard that won't let it use battery juice, even if Windows 8.1 says it's 100% charged.

I've tried the hold the power button down for 1 min with the battery out trick to no avail.

Any ideas? I'm stumped and think I might need to get her another notebook.

Thanks, Robert

My own notebook (Asus EEE PC S101), running Windows XP service pack 3) was twice redirected to an unknown website when I wanted to visit the Guardian newspaper website. I was using IE version 8. Then the notebook froze. When this happened, I had to switch it off without using Cleanup, which I have used safely for a long time. When I had switched it on again, I used Firefox to go to the Techsupport Forum. I followed the instructions to download dds.scr and began running it. Then the notebook froze again. It still tells me "Two logs shall be created on your desktop" Now the cursor does not move any more either. I write this from another notebook, but I cannot create a logfile,m as everything is frozen on my own notebook. Help, please,

New here and so I hope that I am posting in the correct place.
My new notebook an M50-MX5 was in the warranty depot as we thought it had a dvd burning problem, however that was not the case; it was the media.

Anyway before it was sent into the toshiba warranty depot the level 2 tech phone support said to get the computer to be like it was when I unboxed it 2 days earlier, this was last month.
And so to my frustration all of my programs were removed, however before doing this the software techie at the office Ghosted it to my Western Digital Storage Unit and then sent it off to the Warranty Depot.

While it was in the shop I used my 3 yr old toshiba satellite 2410 which I am now typing on at this moment.
I was finally able to get the software tech from the office to reGhost my new toshiba M50 on this past Saturday and left it with him for a couple of hrs and then returned to pick it up as there was not much in the way of programs on it and so it wouldn't take long to Ghost the Images back.

Well, in my Western Digital Storage unit are Ghosts of this 3 year old satellite that I am presently using.
After the techie got my Restore Disk installed and tried to reGhost the image onto the New M50, it crashed.

He was using the wrong Ghost, he was using the one that was from this unit???
I was not happy, especially after he claimed that he now had it Ghosted with the proper Image and I tried it out and it was very sloooooow to Boot. He said it was my Norton 2006.

Something you might want to try (it's a pita) is a repair of windows - this may fix some of the slowness issues you're seeing. The install program he's talking about is probably the U3 component of many larger USB pen drives. I think it's on most of Sandisk's newer large drives. A repair of windows might also take care of this. I seriously doubt that putting the wrong image on the machine and then putting another image on could do any damage to the machine itself - the folks here at my job do it all the time.

A:Resetar BIOS Notebook B490 / Reset BIOS Notebook B490

Check bios entries for boot order and disable PXE (network) boot. Also run diagnostics on HDD while in BIOS and check to see if HDD problems show up.Last - if no hard drive issue is present, and your computer says no system disk present you may have an issue with Windows OS or the boot loader it uses. Boot from Windows DVD or EasyBCD emergency disk to repair any issues with the Windows boot loader.Good luckCB

My HP Pavilion dv9300 series laptop's display is shot. I think it's the motherboard that is creating the problem. The only way to get a display to show up is using an external monitor and disabling the NVIDIA graphic drivers. From what I've read, the MB is overworking the graphics card, causing it to overheat and fry. There was a recall for a number of notebooks that had this problem, but mine did not have the proper product number so HP will not fix it (without making me pay $425). Is anyone out there familiar with this issue and if so, what would be the best (cheapest and most effective) way to resolve it? Thank you!

HP Pavilion dv9334us, Intel Core 2 Duo, NVIDIA GeForce Go 7600, running Vista 32-bit.

Hi! A friend of mine is entering nursing school and couldn't believe the price of textbooks. He found that he can get the books in pdf form at a considerably lower price. I told him he could use a laptop or notebook. However, he doesn't want to buy a laptop or a notebook to use in class. He'll be taking notes in class, as well as following in the pdf textbook. Will something like a kindle have a keyboard and that capability? Is there anything else he could use besides a laptop or notebook? Any and all responses will be greatly appreciated. Thanks.

I have a dell inspiron 4000 notebook that has no CD Rom drive and no floppy drive, I plan to buy a external CD Rom to use with ny notebook but some question arise, (1) if I format my hardrive and install a new OS before the OS is install would the computer recognized my external CD Rom? (2) If I can't use my CD Rom then would it better to buy an hard drive adapter to hook it up to my desktop PC and format the notebook hard drive and install the OS from that machine( ONLY THE OS NOT THE DRIVER FOR ANY EQUIPMENT)

A:CD Rom for notebook

1. Since the external cd rom device would probably be a parallel port or USB kind, the computer will not see it before you install the OS
2.No . Hooking up the laptop hdd and formated, it's ok no problem there, but once you install the OS on it , the OS will try to install the drivers for whatever the hardware is inside the PC. For instance , let's say that the laptop has a Intel chipset , and the desktop has a VIA chipset, well the OS will try to install the drivers for the VIA and you need the Intel ones..
Best you can do is to make sure that the cd rom driver that you will buy cames with DOS drivers . Then format the hard drive on the laptop ( using the desktop machine ) and install the cd rom DOS drivers on it. Then hook up the hard drive back to the laptop and connect the cd rom drive. Boot up and you should have access to the cd rom drive at that point.

I am really having a hard time finding the actual model DV7 notebook I have. The tag on the bottom only says DV7 and there are so many additional numbers ie: Dv7-1001, 1002 etc when u try to look up drivers. I am having a really hard time getting my Blue Ray drive to play any Blue Ray discs and need to find whatever drivers make it work after upgrading to Windows 7 64bit. Any help would be appreciated because it is really frustrating. I've tried every driver I can find from HP and Cyberlink and nothing lets me play all my discs. Mainly anything newer than 2 years ago won't play at all. The drive is spinning it and the drive shows a Blue ray in the description but it says Load disc and doesn't do anything from there. It worked perfectly until i went to Win 7. I even tried the Vista drivers in the Recovery console but still won't work. Thank you for any help.

I have a two and a half year old Compaq notebook maxed out at 2GB Ram that came with Vista. As soon as it was out of warranty, I wiped the hard drive and installed XP Pro. I've run W7 Upgrade Advisor and it says W7 will run on my machine. My question is does it matter which version (Home Premium, Professional, Ultimate) and which bit (32/64) to get the fastest system? Most of what I use it for is the internet and email. Maybe some video. Not a heavy duty user.
